Preventing the Motor from Stalling (Current
Limit)
This function automatically adjusts the output frequency and output cur-
rent according to the load to continue operation without stalling the
motor.
Stall Prevention (Current Limit) Level during Acceleration
(n093)
Sets the stall prevention (current limit) level during acceleration in units
of 1%. (Inverter rated current = 100%)
Factory setting: 170%
A setting of 200% disables the stall prevention (current limit) during
acceleration. If the output current exceeds the value set for n093 during
acceleration, acceleration stops and the frequency is maintained. When
the output current goes to the value set for n093, acceleration starts.
